Safe Warnings and Precautions

Davit cranes are perfect for permanent or portable installation. These cranes consist of an angled beam which pivots over a vertical axis. They can have fixed or adjustable booms, and are available in portable as well as stationary units. Davit cranes incorporate a hand operated and cable assembly forload handling. Independent bases (Optional-Sold Separately) allow you to move the davit crane from base to base, so one davit crane can serve more than one lift station. Standard davit cranes feature an electrostatic powder coating to resist corrosion. Galvanized and stainless steel models provide added protection in harsh environments.

Davit Cranes Series 500 lb, 1,000 lb and 2,000 lb Hand or power winch operation up to 2000 lb capacity

operated models include spur gear or worm gear hand winch with automatic disc brake for load control.

When using this crane, safety precautions should always be followed to reduce the risk of personal injury and damage to the crane.1) Read and follow the guidelines set forth in this owner’s manual. Keep the manual, and all decals adhered to the crane at all times.2) Inspect all components of the crane according to owner’s manual before operation.

should be properly dressed (hard hat, safety shoes and safety glasses, no loose clothing).4) Operators must know the load and the load must not exceed the crane rated capacity.5) The load must be clear of other objects and free to move. Make sure the load will not tip, spin, roll away, or in any way move uncontrollably.

centered over the load uld damage the crane or cause the load to tip.7) When adjusting the boom, set the boom angle a bit above horizontal and hold the boom extension firmly to avoid it sliding out of the boom causing damage or injury.

8) Keep at least 5 wraps of wire rope wound on the drum of the winch at all times, to serve as anchor wraps. With less than 5 wraps on the drum the wire rope could come loose, causing the load to fall off.9) Keep hands away from sheaves, gears, wire rope, and other moving parts of the equipment.10) Keep all unnecessary personnel away from the crane while in operation. Keep out of the path of the load.11) Do not lift people. The crane is not designed for lifting people.

8. Installing the wire rope: 1) Pass the wire rope over the sheave at the end of the boom. See Figure 10.

2) Insert the steel cable through the square hole from inside to outside. Insert the steel cable into one side of the cable anchor. Insert the cable end into the other side of the cable anchor leaving a large loop outside. Tighten the nut slightly. Pull and reduce the loop down to the cable anchor . (See Figure.11)

Instructions for Assembling the 1,000lb/2,000lb Crane

1. There are two kinds of base：pedestal and socket. After

installing the base, install the nylon sleeve on its top.

See Figure 12.

2. Assembling the crane:

1) Install the mast in the base. Move the mast side to side to

make sure the bottom of the mast properly seats on the

pin in the bottom of the base. See Figure 13.

2) Fasten the boom to the mast with the clevis pin which is

secured in place by the lynch pin. The lynch pin is fixed

with the carrying handle by the wire rope. Pay attention

that the carrying handle on the boom should be located

on the same side as the handle on the mast. See Figure 14.

3) First adjust the ratchet jack to the greatest length and then

install it when the boom is at horizontal position. Apply the

clevis pins to secure the two ends of the ratchet jack to the

mast and boom respectively. The clevis pins are fastened

tight by the lynch pins. The lynch pins are fixed with

carrying handles by the wire rope. See Figure 15.

4) Slide the boom extension into the boom and secure in place

with the clevis pin and lynch pin provided. The lynch pin is

fixed with the carrying handle by the wire rope. Please see

the assembly drawing below. See Figure 16.

5) Attach the sheave with the clevis pin while using the cotter

pin to prevent the clevis pin from falling off. Bend the cotter

pin properly so as to secure itself in place. See Figure 17.

7) Install the handle on the lower end of the boom, applying

the clevis pin and lynch pin provided. The lynch pin is fixed

with the carrying handle by the wire rope. See Figure 19.

8) Secure the hand winch to the mounting plate (Figure 20)

using hardware.

9) Install the handle onto the hand winch and tighten the

fastening screw. See Figure 21.
